Specific implementation mode
Fig. 1 to Fig. 5 below in conjunction with the accompanying drawings is described in further detail the D column top connection structures of the present invention.
The D column top connection structures of the present invention, please refer to Fig.1 on Fig. 5, including side-wall outer-plate 1, side-wall inner-plate 2, D columns plus
Strong plate 3, top cap rear cross beam outside plate 5, top cover rear cross beam internal plate 4, the D columns upper reinforcing plate 3 and 1 head and the tail side of the side-wall outer-plate
Connection, side-wall inner-plate 2 are connect with 4 opposite side of the top cover rear cross beam internal plate, and the side-wall inner-plate 2 is reinforced on the D columns
3 end of plate connects, and the top cap rear cross beam outside plate 5 is connect with the head end of the side-wall outer-plate 1, further includes D columns stiffening plate 6, institute
State D columns stiffening plate 6 be a side opening 10 frame-shaped board, the D columns stiffening plate 6 respectively with the D columns upper reinforcing plate 3 and the side
The connection of inner panel 2 is enclosed, closed cavity is formed between the D columns upper reinforcing plate 3 and the side-wall inner-plate 2 and the D columns stiffening plate 6
9.In this way, the increased frame-shaped board with opening 10, that is, D columns are mended between D columns upper reinforcing plate 3, side-wall inner-plate 2, side-wall outer-plate 1
Strong plate 6 so that outside D columns upper reinforcing plate 3 and side-wall inner-plate 2, side-wall outer-plate 1 and top cover rear cross beam internal plate 4 and top cap rear cross beam
5 direct or indirect connection of plate together, improves the bonding strength of D column joints so that the stress point of D column joints disperses, and keeps away
Exempt from stress concentration, therefore avoid inducing crackle, the phenomenon that avoiding result in fatigue fracture and influence to use safely.In addition, by
Closed cavity 9 is formed between the D columns upper reinforcing plate 3 and the side-wall inner-plate 2 and the D columns stiffening plate 6.Closed chamber
Body 9 forms closed cross-section, can effectively improve the torsional moment of inertia and torsion stiffness of D column joints, reduces tail-gate frame deflection, and
And it improves eigentone, avoids resonance and abnormal sound.This have the advantage that structure is simple, improves in terms of existing technologies
The bonding strength of D column top connections, it is possible to prevente effectively from stress concentration, and the torsional moment of inertia of D column top connections can be improved, subtract
Small tail-gate frame deflection improves eigentone, avoids resonance and abnormal sound.It is detected into overtesting, on the D columns using the present invention
Street corner structure, 10 deflection of tail-gate frame maximum open reduce 6%, and tail-gate frame single order torsion mode performance improves 0.38Hz, tail-gate
Frame maximum stress value reduces 27%, and cracking risk is substantially reduced, and vehicle torsion stiffness improves 4.9%.
The D column top connection structures of the present invention please refer to Fig.1 and may be used also on the basis of the technical solution described in front to Fig. 5
To be：3 inside of the D columns upper reinforcing plate is connect with the D columns stiffening plate 6,3 outside of the D columns upper reinforcing plate and the head cover
Rear cross beam outside plate 5 connects.In this way, 3 inner side and outer side of D columns upper reinforcing plate is separately connected D columns stiffening plate 6 and top cap rear cross beam outside plate
5, the stress of dispersion D columns upper reinforcing plate 3 further effectively avoids stress concentration.Further preferred technical solution is the D columns
Stiffening plate 6 includes straight panel 7 and two extension boards 8 from the straight panel 7 to same side that extend from, shape between described two extension boards 8
At the opening 10, the extension board 8 of the D columns stiffening plate 6 is connect with 4 intermediate ends of the top cover rear cross beam internal plate, on the D columns
3 leading inside of reinforcing plate and outside respectively with outside another extension board 8 of the D columns stiffening plate 6 and the top cap rear cross beam
The end of plate 5 connects.Such D columns stiffening plate 6 may be implemented multiple points and be connect respectively with D columns upper reinforcing plate 3, side-wall inner-plate 2,
And form closed cavity 9 with D columns upper reinforcing plate 3 and side-wall outer-plate 1.In addition, the D columns stiffening plate 6 of this spline structure is simple in structure,
Forming is easy, at low cost.Technical solution still more preferably is the D columns upper reinforcing plate 3 and the top cap rear cross beam outside plate 5
And it is corresponding with D columns 6 link positions of stiffening plate.In this way, D columns upper reinforcing plate 3, D columns stiffening plate 6 and top cap rear cross beam outside plate
For the mutual stress of 5 threes on the contrary, offsetting impact force, shock absorbing avoids stress concentration.Technical solution still further preferably is institute
D columns stiffening plate 6 is stated with 4 link position of the top cover rear cross beam internal plate and the D columns stiffening plate 6 and the D columns upper reinforcing plate 3 to connect
Connect position correspondence.In this way, 8 stress of extension board at 6 both ends of D columns stiffening plate on the contrary, further offset impact force, avoids stress collection
In.
The D column top connection structures of the present invention please refer to Fig.1 and may be used also on the basis of the technical solution described in front to Fig. 5
To be：The D columns upper reinforcing plate 3 is identical as side-wall inner-plate 2 and 1 link position of the side-wall outer-plate, 2 end of the side-wall inner-plate
The end inner side and outer side of the D columns upper reinforcing plate 3 is connected to 1 end of the side-wall outer-plate.In this way, effectively dispersion is made
Firmly, partial action power is offset, stress concentration is avoided.Further preferred technical solution is the opening of D columns stiffening plate 6 10 1
Side is arranged towards 3 end of D columns upper reinforcing plate or the D columns stiffening plate 6 is open, and 10 sides add on the D columns
It is arranged at 3 terminal position of strong plate.Especially preferably the opening of D columns stiffening plate 6 10 is towards at 3 terminal position of D columns upper reinforcing plate.This
The closed cavity stability of sample, formation is more preferable, improves the bonding strength bigger of D column joints.Because of the straight panel 7 of D columns stiffening plate 6
Distance D column joints closer to.
It is above-mentioned that only several specific embodiments in the present invention are illustrated, but can not be as the protection model of the present invention
Enclose, it is every according to the present invention in design spirit made by equivalent change or modification or equal proportion zoom in or out, should all
Think to fall into protection scope of the present invention.
