Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
Embodiment：Referring to Fig. 1 to Fig. 5.
A kind of automotive trim structure, including ceiling trim panel 1, A vertical column internal decoration plates, B vertical column internal decoration plates, C vertical column internal decoration plates,
Line of weakness 4 is set from A studs 2 through C studs 3 and close to top handrail and pillar region on ceiling trim panel 1；
V-groove 5,5 mouthfuls of wide 2mm of V-groove and depth are set at ceiling trim panel 1 and the circular arc-shaped corner of each vertical column internal decoration plate overlap joint cambered surface
3mm；At the whole faying surface edge of ceiling trim panel 1 and each vertical column internal decoration plate overlap joint, undaform notch is set；A vertical column internal decorations
Plate and the amount of lap of ceiling trim panel 1 are 6 ~ 8mm；B vertical column internal decoration plates are 8 ~ 10mm or so with the amount of lap of ceiling trim panel 1, vertically
Direction amount of interference about 2 ~ 3mm；C vertical column internal decoration plates and the amount of lap of ceiling trim panel 1 are 10mm or so, vertical direction amount of interference about 2 ~
3mm。
A, B, C vertical column internal decoration plate use is more than 50kj/m under impact strength normal temperature2, it is more than 3kj/m under low temperature2MODIFIED PP
Material is made.
The utility model specification：Ceiling trim panel material takes common used material, such as PU base materials, non-woven fabrics, glass
Fine layer, precoat.Due to reason existing for fiberglass layer so that ceiling also has certain degree of hardness, on the corner more very, it is likely that shadow
Sound skids off to gas curtain.Line of weakness designs：Lateral edges are comprehensive under three kinds of high temperature, normal temperature, low temperature states according to initial several separate explosions
Path, sketch the contours reduction and thread path and line of weakness be embodied on product by repairing a die.During explosion, ceiling stress will be along weak
Change the bending of line trend, merge out breach, maximum possible deformation causes gas curtain goes out from gap smoothly to skid off.Line of weakness depth about product
The 1/2 of thickness, reduction line position typically runs through C studs from A studs, close to top handrail and pillar region.V-groove mouth
Design：V-type notch design is intended to weaken the position of ceiling and column overlap joint cambered surface crankshaft fillets stress concentration to resistance caused by explosion.
V-groove is located at faying surface circular arc-shaped corner, slot opening about 2mm, deep about 3mm.The ironed notch design of undaform：Undaform notch is set
Meter is intended to reduction and overlaps out ceiling arc deformation stress, and position is whole faying surface edge.
A vertical column internal decoration plates are the 1st stress concentration points of explosion moment.Gas curtain opens moment, and cord is from crimped configuration toward car
Interior expansion, cord front end fixed pulling rope moment tighten, and A columns plaque is shaken off from metal plate part concedes space, cord from A columns with
Ceiling overlap joint skids off in gap.A vertical column internal decoration plates are 6 ~ 8mm or so with ceiling amount of lap recommended value.Amount of lap is too small in vehicle
Have the risk of crack under tolerance is accumulative, amount of lap is excessive, can increase resistance of gas curtain moment when opening so that explosion it is sluggish or
Person's trim panel stress crushes sputtered debris.A vertical column internal decoration plates and the edge of ceiling overlap joint, its thickness suggestion do gradual change and place are thinned
Reason, so that cord skids off, cut down stress concentration.
B vertical column internal decoration plates are located near trigger, are the 2nd stress concentration points of explosion moment, are acted on by gas curtain toward lower end
Impulsive force, and gas curtain expands the power toward in-car direction.Opened from the B vertical column internal decoration plates of adopting guiding structure design in gas curtain
When, it is oriented to slope and guides cord from B columns with being skidded off in ceiling overlap joint gap.Here, it is 8 with ceiling design amount of lap recommended value
~ 10mm or so, vertical direction amount of interference about 2 ~ 3mm.The too small risk for having crack in the case where vehicle tolerance is accumulative of amount of lap, amount of lap
It is excessive, resistance during gas curtain moment opening can be increased so that explosion is sluggish or trim panel stress crushes sputtered debris.B columns
The edge of trim panel and ceiling overlap joint, gradual change reduction processing is done in its thickness suggestion, so that cord skids off, cuts down stress concentration.
C vertical column internal decoration plates are 10mm or so, vertical direction amount of interference about 2 ~ 3mm with ceiling design amount of lap.For second
Row's seat also increases the vehicle of CAB configurations, and C column plaques belong to gas curtain expansion end, and Impact direction is toward in-car direction.Design is taken
The too small risk for having crack in the case where vehicle tolerance is accumulative of the amount of connecing, amount of lap is excessive, can increase resistance during gas curtain moment opening,
So that explosion is sluggish or trim panel stress crushes sputtered debris.C vertical column internal decoration plates and the edge of ceiling overlap joint, its thickness suggestion
Gradual change reduction processing is done, so that cord skids off, cuts down stress concentration.
What embodiment of the present utility model was announced is preferred embodiment, but is not limited thereto, the common skill of this area
Art personnel, easily according to above-described embodiment, understand spirit of the present utility model, and make different amplification and change, but as long as
Spirit of the present utility model is not departed from, all in the scope of protection of the utility model.
