Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile accessories, in particular to a roof air outlet. BACKGROUND

[0002] The automobile roof air outlet assembly is generally installed on the roof of a business car or a passenger car, and functions to regulate and ventilate the temperature inside the car. The automobile roof air outlet assembly generally comprises an air outlet panel, an air outlet body and a blade. The air outlet panel and the air outlet body are often connected to each other by using elastic buckles made of plastic material. When the air outlet body is directly inserted into the air outlet panel, the elastic buckles are automatically clamped with the air outlet panel. This arrangement facilitates the quick installation of the air outlet body.

[0003] The automobile roof airbag is installed in the roof above the passenger, and comprises a gas generator, a gas bag and a gas generator shell. When the airbag works, the high-temperature and high-pressure gas generated by the gas generator is guided through the gas generator shell to inflate the gas bag, so that the airbag is smoothly unfolded to achieve the function of protecting the passenger.

[0004] However, when the roof airbag of the automobile is ejected, a huge impact will be generated, which will further cause the air outlet panel and the air outlet body to deform. This will cause the air outlet body to be taken out of the air outlet panel along with the ejection of the airbag. When the taken-out air outlet body impacts the human body, it will cause great harm to the human body. SUMMARY

When the air frame 1 is inserted into the mounting hole 21 in the vertical direction, the lower side of the locking inclined plate 413 will be deformed towards the second plate 412, and after the air frame 1 is installed in the mounting hole 21, the lower side of the locking inclined plate 413 will abut against the upper side of the limiting snap ring 42. The locking inclined plate 413 can realize the locking of the limiting snap ring 42 and the limiting snap plate 41 in the vertical direction.

[0053] The locking inclined plate 413 provided on the second plate 412 can be one or two. When one locking inclined plate 413 is provided, the locking inclined plate 413 is provided on the side of the second plate 412 away from the automobile roof airbag; when two locking inclined plates 413 are provided, the locking inclined plates 413 are provided on both sides of the second plate 412 in the thickness direction. Therefore, when the airbag is ejected and drives the air frame 1 to be ejected from the mounting plate 2, at this time, the second plate 412 moves in the limiting snap ring 42, and the lower side of the locking inclined plate 413 abuts against the upper side of the limiting snap ring 42, at this time, the second plate 412 cannot be separated from the limiting snap ring 42, the locking inclined plate 413 locks the limiting snap ring 42 and the limiting snap plate 41 in the vertical direction, and the possibility of the air frame 1 being driven out by the airbag is reduced.
