Description
Technical field
The utility model relates to a kind of automobile ceiling structure, and especially a kind of ceiling structure of equipped side air curtain device vehicle belongs to the body structure technical field.
Background technology
Progress along with auto manufacturing technology, the safety performance of automobile more and more receives customer's concern, the medium-to-high grade vehicle of most all has been equipped with safety air bag and side air curtain device, wherein the radical function of side gas curtain is: when automobile generation side impact and rolling, ensure passenger's life security.Because the side gas curtain generally is installed on the Sheet Metal Part of body side wall top (referring to Fig. 1), the side gas curtain opens the clamping power that will overcome ceiling deformation resistance, ceiling and door frame sealing band friction drag, ceiling and column plaque friction drag and column plaque and Sheet Metal Part when quick-fried, ejected to driving compartment by ceiling and body side wall interior trimming parts joining place, therefore the mounting structure of vehicle body ceiling and column plaque and door frame sealing band is the key factor that restriction side gas curtain ejects smoothly, also is one of the problem that must consider in the body structure design.
In the existing ceiling mounting structure; side gas curtain ejection door place strength of parts is larger; the side gas curtain open when quick-fried and ceiling, column plaque and door frame sealing band between friction drag larger, be unfavorable for that the side gas curtain enters driving compartment smoothly, affected the performance of side gas curtain safety guard-safeguard effect.
The utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of simple in structure, dependable performance, enforcement to be convenient to easily the automobile ceiling structure that the side gas curtain ejects.
Problem described in the utility model realizes with following technical proposals:
A kind of automobile ceiling structure of being convenient to the ejection of side gas curtain, it comprises ceiling base material and ceiling fabric, described ceiling fabric is coated on the outside of ceiling base material, described ceiling base material is installed on the top cover sheet metal structural parts, and its special feature is: in ceiling base material arranged on left and right sides edge breach is set evenly.
The above-mentioned automobile ceiling structure of being convenient to the ejection of side gas curtain, described ceiling base material arranged on left and right sides breach overlaps with front truck sealing strip for door frame, tail gate frame sealing band respectively at front truck doorframe and tail gate frame position, and is hidden by the edge of front truck sealing strip for door frame, tail gate frame sealing band.
The above-mentioned automobile ceiling structure of being convenient to the ejection of side gas curtain, described ceiling base material arranged on left and right sides breach overlaps with vehicle body front pillar plaque, vehicle body center pillar plaque and vehicle body rear pillar plaque respectively in vehicle body front pillar, vehicle body center pillar and vehicle body rear pillar position, and is hidden by the flange of vehicle body front pillar plaque, vehicle body center pillar plaque and vehicle body rear pillar plaque.
Ceiling base material of the present utility model has reduced ceiling side gas curtain and has ejected the intensity at position at edge, left and right sides design breach, thereby has reduced the ceiling deformation resistance that bears when the side gas curtain opens quick-fried the ejection, is conducive to the side gas curtain and enters smoothly driving compartment; At ceiling base material gap position place, ceiling base material innner and outer side ceiling fabric forms cavity, reduced the pressure of ceiling and door frame sealing band, ceiling and column plaque overlapping part, thereby the friction force when having reduced the side gas curtain and ejecting is conducive to opening of side gas curtain quick-fried and eject more; Ceiling base material arranged on left and right sides breach major part of the present utility model is hidden by vehicle body sealing strip for door frame and body upright post plaque flange, fail to be coated by the ceiling fabric by the part of vehicle body sealing strip for door frame and the covering of body upright post plaque flange, not only guarantee the sealing function of driving compartment, and improved the decorative effect of driving compartment.The utility model is simple in structure, practical, dependable performance, can guarantee the smooth ejection of side gas curtain when vehicle generation side impact and rolling accident, has demonstrated fully the safety protection function of side gas curtain.
