Description
Technical field
Technical field of automobile parts is the utility model is related to, in particular to a kind of roof of the vehicle auxiliary security gas curtain exhibition
The weakening structure opened.
Background technology
In order to protect occupant safety, car enterprise is directed to vehicle and relevant parts, has carried out various safety tests, in automobile
The side curtain airbag explosion bulge test adornd on ceiling is exactly one of which.Side curtain airbag is installed on inner decorative ceiling side and the inner decorative ceiling of automobile
In the space that adjacent trim panel is formed with vehicle body, when vehicle crashes, side curtain airbag should be able to be smoothly from interior trim top
Canopy side release, to protect the safety of occupant.Since the material that inner decorative ceiling uses has preferable toughness and hardness, doing
During side curtain airbag explosion bulge test, inner decorative ceiling comes off highly difficult from B columns, C column trim panels junction, causes side curtain airbag by B columns, C
Column trim panel tangles, prevent side curtain airbag when shock accident occurs from be discharged into up to designated position and it is ineffective.This practicality is new
The purpose of type, is on the basis of existing inner decorative ceiling structure is constant, in inner decorative ceiling two sides, close inner decorative ceiling is adjacent
Trim panel junction is improved on position, and when the vehicle is crashed, side curtain airbag can be released easily from inner decorative ceiling
Position is put into, so as to reach protection occupant's purpose.
Utility model content
In view of the above shortcomings of the prior art, technical problem to be solved in the utility model is：How a kind of knot is provided
Structure simple shape, while the aesthetics of interior trim is ensured, can be such that safe air curtain is smoothly discharged from ceiling, be conducive to improve whole
The weakening structure of the roof of the vehicle auxiliary security inflatable curtain deployment of car security.
In order to solve the above-mentioned technical problem, the utility model employs following technical solution：
A kind of weakening structure of roof of the vehicle auxiliary security inflatable curtain deployment, including inner decorative ceiling, the width of the inner decorative ceiling
The both sides in degree direction are respectively provided with the reduction groove set along its length, it is characterised in that have on the reduction groove along its length
The notch that direction is set is spent, the notch is set along the length direction equi-spaced apart of the reduction groove.
Since the material that inner decorative ceiling uses has preferable toughness and hardness, notch is set on reduction groove, can be dropped
The toughness and intensity of lowization groove so that can easily destroy reduction groove after safe air curtain expansion, and be discharged from ceiling, be played
The effect of security protection, said structure simple shape are carried out to occupant, and does not influence the appearance of existing inner decorative ceiling, ensure that
The aesthetics of inner decorative ceiling, enhances the security of vehicle.
Further, the reduction groove includes being arranged at intervals the first reduction groove along the length direction of the inner decorative ceiling, with
And the second reduction groove of the corresponding setting of interval location between the two neighboring first reduction groove, the second reduction groove
Length be more than spacing between two the first reduction grooves, and be respectively less than with the spacing of two the first reduction grooves described
Weaken the width of groove.
Using the above structure, groove subsection setup will be weakened, whole inner decorative ceiling can be reduced to avoid long reduction groove
Intensity, is conducive to take into account the aesthetics and feature of inner decorative ceiling.
Further, the reduction groove is male type groove body or inner concave shape groove body.
Further, the incision of the reduction groove is filled with ceiling base material and Roof shell fabric.
Further, the thickness of the inner decorative ceiling is 8~9mm, and the thickness of the reduction groove is 4~5mm.
Further, the length of the notch is 15~25mm, and the spacing of the two neighboring notch is 10~20mm.
In conclusion the utility model has, planform is simple, while the aesthetics of interior trim is ensured, can make peace
The advantages that full gas curtain smoothly discharges from ceiling, is conducive to improve vehicle security.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment.
Fig. 2 is the enlarged structure schematic diagram of the circled in Fig. 1.
Fig. 3 is the structure diagram of the notch of reduction groove.
Embodiment
With reference to embodiment, the utility model is described in further detail.
During specific implementation：As shown in FIG. 1 to 3, a kind of weakening structure of roof of the vehicle auxiliary security inflatable curtain deployment, it is described
The both sides of the width of inner decorative ceiling 1 are respectively provided with the reduction groove 2 set along its length, it is characterised in that the reduction
There is the notch set along its length, the notch is set along the length direction equi-spaced apart of the reduction groove 2 on groove 2.
Since the material that inner decorative ceiling uses has preferable toughness and hardness, notch is set on reduction groove, can be dropped
The toughness and intensity of lowization groove so that can easily destroy reduction groove after safe air curtain expansion, and be discharged from ceiling, be played
The effect of security protection, said structure simple shape are carried out to occupant, and does not influence the appearance of existing inner decorative ceiling, ensure that
The aesthetics of inner decorative ceiling, enhances the security of vehicle.
During implementation, the reduction groove 2 includes being arranged at intervals the first reduction groove 21 along the length direction of the inner decorative ceiling 1,
And the second reduction groove 22 of the corresponding setting of interval location between the two neighboring first reduction groove 21, described second
Weaken groove 22 length be more than two it is described first reduction groove 21 between spacing, and with two it is described first reduction groove spacing
The width of respectively less than described reduction groove 2.
Using the above structure, groove subsection setup will be weakened, whole inner decorative ceiling can be reduced to avoid long reduction groove
Intensity, is conducive to take into account the aesthetics and feature of inner decorative ceiling.
During implementation, the reduction groove 2 is male type groove body or inner concave shape groove body.
During implementation, the incision of the reduction groove 2 is filled with ceiling base material and Roof shell fabric.
During implementation, the thickness of the inner decorative ceiling 1 is 8~9mm, and the thickness of the reduction groove 2 is 4~5mm.
During implementation, the length of the notch is 15~25mm, and the spacing of the two neighboring notch is 10~20mm.
The above is only the preferred embodiment of the utility model only, all at this not using the utility model as limitation
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
