A kind of automobile central post trim panel
Technical field
The utility model relates to a kind of vehicle body interior trimming parts, especially relates to a kind of automobile central post trim panel.
Background technology
Along with a large amount of of automobile popularize, the generation of traffic accident is also more and more, and people pay attention to protecting the life security of self more.Because side impact, it is very big to the harm that human body causes that traffic accident takes place, and assembled safety air bag on the therefore increasing automobile, the safety air bag of side, and promptly gas curtain more and more is subjected to people and pays close attention to.For vehicle generation side impact time protection driver and passenger, in the door installed inside gas curtain, when vehicle generation side impact, launch the side gas curtain by charging blower, driver and passenger are protected.Gas curtain is installed in the roof arc steel fine strain of millet, before and after running through usually, controlled by the interior lateral acceleration sensor of vehicle body.When transverse acceleration greater than normal value, and will control when reaching dangerous values and detonate, gas curtain for side hit, major accident such as overturning has good personal protection function.
But because vehicle body trim panel structure design is reasonable inadequately; gas curtain detonates the back stretching, extension rapidly; there is not fixing direction of extension; the impulsive force of to interior is too strong; when serious the vehicle body trim panel is come off or breakage; cause interior trimming parts to tangle gas curtain, cause gas curtain can not in time protect Che Nei driver and passenger, can't play due effect.
As notification number be: the B-post assembly parts of a kind of improved auto body of CN2846261Y, relate to the B-post assembly parts of auto body, the section that it is characterized in that brace panel is a complete flute profile, and outward extending limit of notch and the fixing overlap joint of median septum.This patent exists does not have the suitable guide structure, and to interior caused stronger impulsive force after gas curtain detonated, and trim panel is come off or breakage, causes interior trimming parts to tangle gas curtain, and gas curtain can't play the problem of due effect.
Summary of the invention
The utility model mainly is after detonating at the existing gas curtain of existing central post trim panel, trim panel is come off or fragmentation, can tangle gas curtain, the problem that causes gas curtain normally not detonate, provide a kind of space of inflatable curtain deployment less relatively, and inflatable curtain deployment is had directional tagging, and gas curtain is not easy a kind of automobile central post trim panel of being tangled.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of automobile central post trim panel, and the upper end of central post trim panel is connected with guide plate, and the end of described guide plate is connected with the positioning plate with roof rail inner panel overlap joint.Increase a kind of guide plate newly in the upper end of central post trim panel, the other end of this guide plate connects positioning plate, and positioning plate is overlapped on the end of roof rail inner panel, and gas curtain is installed between this guide plate and the ceiling.After gas curtain detonates like this; guide plate can play the effect of guiding and restriction gas curtain direction of extension; gas curtain will stretch rapidly outside car by the lap-joint of guide plate and ceiling along guide plate; the final expansion to protect user's personal safety; avoided there is not guide plate in the conventional confguration, gas curtain launches chaotic in car body, trim panel is come off or breakage; cause coming off or broken trim panel tangles gas curtain, influence the normal use of gas curtain.Positioning plate is overlapped on the roof rail inner panel, and positioning plate plays position-limiting action to guide plate, prevent inflatable curtain deployment after, guide plate displacement influences the use of guide plate.
As preferably, described guide plate is a bending structure, and bending angle is 120 ° ~ 160 °.When gas curtain launched in car body, guide plate can be subjected to stronger impulsive force, and with respect to straight plate, the guide plate of bending structure can increase impact strength, is not easy breakage, can better play the effect that the guiding gas curtain stretches along guide plate.The top margin of guide plate in car direction (outside car direction also can, but effect does not have in the car direction effective), bending angle is 120 ° ~ 160 °, structural strength is higher, guide plate is not easy to damage.
As preferably, described positioning plate be shaped as arc.There is deep-slotted chip breaker the end of roof rail inner panel, and the positioning plate of arc cooperates with the roof rail inner panel, guarantees that guide plate is difficult for landing, and influence is used.
As preferably, be provided with reinforced rib between described guide plate and the positioning plate.Reinforced rib is further strengthened the intensity of guide plate and positioning plate, and it is damaged to prevent that guide plate or positioning plate from taking place.
As preferably, described central post trim panel, guide plate and positioning plate are the integrative-structure of injection mo(u)lding.Integrally manufactured, simple in structure, the intensity height.
Therefore, the utlity model has simple in structurely, the space of inflatable curtain deployment is less relatively, and inflatable curtain deployment is had directional tagging, and gas curtain such as is not easy to be tangled at advantage.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As Figure of description 1,2, shown in 4, a kind of automobile central post trim panel, the upper end of central post trim panel 1 is connected with guide plate 2, guide plate is a bending structure, bending angle is 150 °, the guide plate top margin relies on direction in the car, the end of guide plate is connected with the positioning plate 3 of arc, positioning plate cooperates with deep-slotted chip breaker on the roof rail inner panel 4, guide plate and positioning plate adopt the ABS(acrylonitrile-butadiene-styrene copolymer) make, the ABS material has characteristics such as strength under shock height, and the both sides of guide plate and positioning plate are provided with reinforced rib 5, the central post trim panel, guide plate and positioning plate are the integrative-structure of injection mo(u)lding.
When the serious side of generation is hit or is overturned; gas curtain 8 can detonate rapidly and to around stretch; guide plate is caused than thump; body inner panel 7 and roof rail inner panel while fixed limit plate; guide plate is difficult for being shifted; the gas curtain that launches launches to guide plate and ceiling 6 lap-joints (being B position in the accompanying drawing 3) along guide plate, stretches out car body at last, and driver and passenger are protected.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
