Automobile instrument implicit expression air-bag support
Technical field
The utility model belongs to the automotive trim field.
Background technology
Domestic-developed design-calculated instrument carrier panel air-bag support mainly is a metallic support, the cost height, and only a few money air-bag supports are to use plastic material, and cost is very high.Mainly be based on the PP polypropylene, dose some auxiliary material, and be not the all-plastic material, what have comprises woven fabric, and the hinge that has is a metallic material, has plenty of metal sandwich, is not the all-plastic exploitation, and cost is still very high.
Ethylene propylene diene rubber TPO is a kind of thermoplastic elastomer.
Summary of the invention
The utility model provides a kind of Automobile instrument implicit expression air-bag support, to solve present metallic support or the high problem of other non-overall plastic material cost.The technical scheme that the utility model is taked is: support is captiveed joint by hinge with two cover plates, and this two cover plates is by the point of connection captive joint, and this support, cover plate, hinge and point of connection are made by overall plastic material.
A kind of embodiment of the utility model adopts ethylene propylene diene rubber TPO material to make.
When installing and using, at first to processings that weaken of the instrument carrier panel of air bag top, the zone that pops of assurance air bag.Secondly air bag module is connected on the air-bag support by front and back side hook, and air-bag support gives the certain support of air bag module and spacing in the blasting process like this; The junction is, and small powder is thick that 0.5mm is only arranged, so junction intensity is minimum, air bag is produced from here during explosion, defines the particular location that air bag pops so the cover plate of air-bag support is arranged, the cover plate of unlatching plays directional tagging to air bag.
The utility model advantage is: be an integral structure; adopt full Shooting Technique production; simple in structure; ethylene propylene diene rubber TPO material property is good, and is cheap, and air-bag support meets the requirements of the standard fully in test; and the air-bag support cover plate can play directional tagging; make air bag along the explosion in the standard time of accurate direction well, make air bag explosion correct position, play protection passenger's effect.

The specific embodiment
Support 1 is captiveed joint by hinge 3 with two cover plates 2, and this two cover plates is by point of connection 4 captive joints, and this support, cover plate, hinge and point of connection are made by overall plastic material;
A kind of embodiment of the utility model adopts ethylene propylene diene rubber TPO material to make.
This practicality is an integral structure newly, adopts full Shooting Technique production,
