Abstract

The utility model discloses a flexible plastic hidden type auxiliary airbag cover plate module structure. The flexible plastic hidden type auxiliary airbag cover plate module structure comprises a hinge (1), weakening grooves (3), an auxiliary airbag cover plate (4), double Y-shaped weakening lines (5), anti-skidding ribs (6), special patterns (7), foaming layers (8), a slush-molded skin (9) and an instrument panel framework (10), and is characterized in that the anti-skidding ribs (6) are uniformly distributed on the surface of the auxiliary airbag cover plate (4), and the distance between the hinge and the nearest anti-skidding rib (6) is 5-10 mm; the height and the width of each anti-skidding rib (6) are 1 mm. In a bursting process of an auxiliary airbag, when the auxiliary airbag cover plate is turned over and the two adjacent foaming layers are extruded, the foaming layers cannot be separated to fly out in the presence of the anti-skidding ribs and the special patterns, so that the safety of passengers is guaranteed.

Description

A kind of soft hidden auxiliary airbag cover modular construction of moulding

Technical field

The utility model relates to a kind of secondary airbag device, relates to specifically a kind of soft hidden auxiliary airbag cover modular construction of moulding, and while being applied to prevent secondary safety air bag explosion, foaming layer and cover plate disengaging fly out.

Background technology

At present, Automobile instrument more than B level is all the soft instrument carrier panel of moulding substantially, secondary safety air bag on instrument carrier panel is all hidden type safety air bag substantially, during soft secondary safety air bag explosion of moulding foaming, foaming layer is outwards overturn by hinge position with interior part with air bag cover plate hinge together with foaming layer, when hinge design is unreasonable, and cover plate or be difficult to outwards upset, be easy to fracture from hinge position, fly out at a high speed, or foaming layer flies out with cover plate disengaging, affect occupant's safety.

Summary of the invention

The deficiency existing in order to overcome above technology, the utility model provides a kind of soft hidden auxiliary airbag cover modular construction of moulding.

The technical solution adopted in the utility model is: a kind of soft hidden auxiliary airbag cover modular construction of moulding, it comprises hinge, weakens groove, secondary airbag cover, two Y shape line of weakness, anti-skidding muscle, special texture, foaming layer, slush moulding epidermis, instrument board framework, it is characterized in that: described anti-skidding muscle is to be uniformly distributed on secondary airbag cover surface, described anti-skidding muscle is arranged into the cut-off from hinge 5～10mm place always, and the height and the width of described anti-skidding muscle are 1mm.

Preferably, the spacing distance between described adjacent anti-skidding muscle is 3～5mm.

Preferably, described special texture is to be uniformly distributed on secondary airbag cover surface.

Preferably, described special texture is round point shape or square shape texture.

Preferably, in described secondary airbag cover, arrange between anti-skidding muscle and special texture post-foaming layer and anti-skidding muscle and form staggered tight connection.

The beneficial effects of the utility model are: on the one hand, in secondary safety air bag blasting process, secondary airbag cover is easy to outwards upset and can does not fracture and fly out from hinge position, thereby has guaranteed occupant's safety; On the other hand, between processing anti-skidding muscle and special texture post-foaming layer and anti-skidding muscle, secondary airbag cover is connected with regard to having formed a kind of staggered close and firm, when in balloonet blasting process, secondary airbag cover is overturn, foaming layer and foaming layer produce extruding, because thereby the existence of anti-skidding muscle and special texture has guaranteed that foaming layer can not depart from and fly out, thereby guaranteed occupant's safety.

The specific embodiment

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the soft hidden auxiliary airbag cover modular construction of moulding, it comprises hinge 1, weakens groove 3, secondary airbag cover 4, two Y shape line of weakness 5, anti-skidding muscle 6, special texture 7, foaming layer 8, slush moulding epidermis 9, instrument board framework 10.Described anti-skidding muscle 6 is to be uniformly distributed in secondary airbag cover 4 surfaces above, and described anti-skidding muscle 6 is arranged into the cut-off from hinge 5～10mm place always, and the height and the width of described anti-skidding muscle 6 are 1mm.Spacing distance between described adjacent anti-skidding muscle 6 is 3～5mm; Described special texture 7 is to be uniformly distributed on secondary airbag cover 4 surfaces; Described special texture 7 is round point shape or square shape texture; In described secondary airbag cover 4, arrange between anti-skidding muscle 6 and special texture 7 post-foaming layers 8 and anti-skidding muscle 6 and form staggered tight connection.

The utility model is when after balloonet blasting process cover plate is torn from two Y shape line of weakness 5, secondary airbag cover 4 is outwards overturn along hinge 1 place, the foaming layer 8 of hinge 1 position and foaming layer 8 produce while pushing due to the existence of anti-skidding muscle 6 with special texture 7, thereby guaranteed that foaming layer 8 can not depart from and fly out, in secondary safety air bag blasting process, secondary airbag cover 4 is easy to outwards upset and can does not fracture and fly out from hinge 1 position simultaneously, thereby has guaranteed occupant's safety.

Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
