Description
Technical field
This utility model belongs to field of automobile, is related to a kind of sheet metal structural of automobile tail gate doorframe top connection.
Background technology
As people require more and more higher to automotive performance, to ensure that the resistance to of automobile touches while lightweight demand is improved
Performance is hit, body torsional rigdity is an important foundation of automobile crash worthiness energy, is also the Basic Evaluation of vehicle structure performance
Index；Body frame appreciable impact body torsional rigdity, particularly load transfer path, section seriality, joint stiffness, closure
The aspects such as loop are all the main points of structure design；But due to being limited by assembly technology, some traditional key joints are only
It is to be connected by single solder joint, forms obvious design defect, causes body torsional rigdity to be affected.Traditional vehicle is often led to
Cross raising material rate, thickened material, increasing section etc. and carry out reinforcement structure, so as to control load transmission, these methods are subject to sky
Between, cost, the influence factor of construction cycle it is larger.
Chinese patent (notification number：CN204701667U, publication date：2015-10-14) disclose a kind of tail-gate door of automobile
Frame assembly, including the connection angle of tail-gate frame entablature, tail-gate frame gusset plate and tail-gate frame entablature and tail-gate frame gusset plate
Place is connected with tail reinforcing structure for door frame, and tail reinforcing structure for door frame is integrally L-shaped, including reinforcing plate and respectively with tail-gate frame
Entablature and the connecting portion of tail-gate frame gusset plate connection, reinforcing plate periphery has been wholely set flange, and connecting portion is overlapped in flange.
Tail-gate doorframe assembly in above-mentioned patent documentation improves the strength and stiffness of tail-gate doorframe by arranging reinforcing plate, but

Its operation principle is as follows：It is connected by single solder joint when vehicle side is assembled with top cover, it is thin that top connection forms connection
Weak area；Analysis shows, herein stress concentration, deformation are larger, and local stiffness is substantially not enough, so as to the torsion of appreciable impact car load is firm
Degree and torsion mode.Inner panel is connected respectively with vehicle side and top cover in the technical program, by arranging in inner panel upper end
Extension, is provided for connecting the connecting portion of automobile tail gate on extension；Weak welding edge link is transferred to firm to reversing
At degree, the less sensitive rear cross beam of torsion mode, in joint complete Path of Force Transfer is formed；So as to improve automobile tail gate doorframe
The rigidity and intensity of junction；Simultaneously as eliminating traditional tail-door hinge installing plate, but it is directly integrated into extension
On, amount of parts is reduced, realize light-weight design.
Body side wall is basically unchanged with the assembly relation and assembling complexity of top cover in the technical program, is not changing car
On the premise of body assemble sequence, specific structure is proposed for part bulk-breaking, the welding position etc. of tail-gate doorframe top connection, improved
The local stiffness of body structure, the overall torsional rigidity so as to improve vehicle body and torsion mode, while inner panel and outside plate are excellent
Change bonding relation, form complete cavity body structure, realize the synchronous improvement of light weight effect and NVH performances.
In the sheet metal structural of above-mentioned automobile tail gate doorframe top connection, the extension by the inner panel upper end arc
It is bent to form.Good load transmission can be so formed, the torsional rigidity of extension bonding strength and extension is improved, is made
Extension bears bigger power when being connected with automobile tail gate and top cover.
In the sheet metal structural of above-mentioned automobile tail gate doorframe top connection, the inner panel is including the internal layer being connected as a single entity and outward
Layer, has cavity between the internal layer and outer layer, have for mutually overlapping with the top cover positioned at the superficies of extension
Step surface.It is so light-weighted in raising inner panel while ensureing the bonding strength and support strength of inner panel.
In the sheet metal structural of above-mentioned automobile tail gate doorframe top connection, the rear cross beam is in long strip-board shape, the top cover
It is overlapped on the upper surface of the rear cross beam；The upper end of the outside plate is relative with the side of the top cover to be connect and is connected.By changing
Become the link position of part, realize the reasonable distribution of structure sensitive degree, reach performance boost and light-weighted effect.
In the sheet metal structural of above-mentioned automobile tail gate doorframe top connection, the length of the extension is that the rear cross beam is long
The 1/5～1/3 of degree.Preferably 1/4；Generally automobile tail gate doorframe top connection structure is symmetrical arranged at rear cross beam two ends, this technology
Scheme is easy to the arrangement of connecting portion on extension, can either be transferred to torsional rigidity, reverse mould weak welding edge link
At the less sensitive rear cross beam of state, it is avoided that connecting portion too close to middle part again.
Compared with prior art, it is provided on extension by arranging extension in inner panel upper end in this utility model
The connecting portion of connection automobile tail gate；By weak welding edge link be transferred to it is less sensitive to torsional rigidity, torsion mode after
At crossbeam, in joint complete Path of Force Transfer is formed；So as to improve the rigidity and intensity of automobile tail gate doorframe junction；Together
When, due to eliminating traditional tail-door hinge installing plate, but it is directly integrated on extension, amount of parts is reduced, it is real
Light-weight design is showed.
